802.11g is an exciting new technology that offers additional performance, while providing investment protection for 802.11b clients through backward compatibility. By using previous technologies and economies of scale, 802.11g devices are available at little or no additional cost relative to 802.11b. As such, there are many reasons to begin migrating from 802.11b to 802.11g.802.11g is not, however, a panacea for WLAN capacity issues. As WLAN capacity needs increase, network professionals are well-advised to begin deploying a dual-band infrastructure to access the far greater capacity available with 802.11a.
